nh3 Measurement for testing

Procedure. Collect a venous blood sample. Note that some institutions require the specimens to be sent to the laboratory in an iced container. Avoid having patient clench fist or using tight tourniquet during blood draw because muscle contraction and ischemia may cause ammonia to be released into venous blood.
